However, dreams are dreams after all, and most of them are just a normal psychological activity of people.
As far as the dreamer's dream is concerned, you dreamed of your great-grandmother. "She" is now living well and her face is rosy. This kind of dream is very comfortable and won't give you a feeling of depression, which is very good. This shows that something that you have been depressed about (something that should be closely related to your family) is beginning to change for the better, which is a good phenomenon. As long as you keep working hard, you will get good results soon. Good luck.
